A facile fabrication method was introduced to enhance the specific surface area and porosity of carbon nanofibers. The nanofibers bearing TiO2 hollow nanosphere electrodes were synthesized using an electrospinning technique followed by heat treatment. Varying amounts as-prepared nanospheres incorporated into polymer precursor examine their impact on electrode enhancement. electrochemical performance supercapacitor composed investigated. Results revealed that capacitance bare (170 F g–1 at a...
Abstract Cement is the most widely used construction material due to its strength and affordability, but production energy intensive. Thus, need replace cement with available waste such as incinerated black filter cake (IBFC) in order reduce consumption associated CO 2 emissions. However, because IBFC a newly discovered replacement material, several parameters affecting mechanical properties of IBFC-cement composite have not been thoroughly investigated yet. this work aims investigate impact...
The comprehensive control of hydroxyapatite, involving morphological and structural variations, particle sizes, defect formations, has garnered considerable attention for its versatile functionalities, rendering it applicable in diverse contexts.
The magneto-optical Kerr effect (MOKE) in monodomain bismuth ferrite (BiFeO3) thin films was investigated under applied electric fields and light irradiation. field-swept MOKE measurements show that the rotation of BiFeO3 changes or piezoresponse force microscopy found variation electrical polarization at surface similar an field ultraviolet irradiation, confirming can be controlled using both This paper presents a method to couple magnetic with irradiation via angle BiFeO3, providing...
Abstract Silver microelectrode arrays are fabricated by photolithography for a one‐step analysis of H 2 O in low ionic strength samples. The effects electrode length, width, band‐to‐band separation, connection height, and adhesion layer evaluated. developed sensor shows excellent repeatability (RSD=1.20 % ( n =5)) reproducibility (RSD=1.12 with the linear range 0.0–10.0 mM, sensitivity 9.84±0.34 μA mM −1 , detection limit 22.69 μM. has been successfully applied to detect directly without...
In this work, we study and compare the photo-induced conductivity of a two-dimensional electron gas (2DEG) at bare surface SrTiO3 (STO) in heterostructure BiFeO3 (BFO) STO, where BFO was deposited by radio frequency magnetron sputtering. The conductance BFO/STO interface shows large increase which is 20.62 times more than sum from each individual thin film STO crystal. Since can be adjusted to become higher lower applying an electric field top surface, attribute strong electrical...
In this work, we study and compare the electrochemical performance of Li-ion battery (LIB) with without a BiFe0.95Cu0.05O3 thin film coating. The is deposited on both LiNi0.5Mn0.3Co0.2O2 (NMC532) cathode graphite anode electrodes using radio frequency magnetron sputtering. By galvanostatic charge–discharge measurements, observe that, in contrast to LIB coating, charging curve coating exhibits counterintuitive negative slope electron compressibility (NEC) rate NEC equal −16.36 × 10−11 meV per...
This work describes the fabrication of a composite supercapacitor electrode made Cu-doped BiFeO $$_3$$ (Cu-BFO) films on an activated carbon (AC) using radio-frequency (RF) magnetron sputtering. To prevent exfoliation Cu-BFO and AC upon immersion in electrolyte, nickel foam sandwiching technique was introduced. The significantly enhanced electrochemical properties, increasing specific capacitance by up to 151% compared that electrode. attributed Faradaic reactions surface area Cu-BFO/AC...
The effect of oxygen on the electrical conductance and local structural properties BiFeO3 (BFO) thin films SiO2/Si substrates grown by RF magnetron sputtering was investigated. conductivities BFO were studied in a planar electrode with blue light irradiation.
